Hello,
my name ist Tom and a build a new Printer.
I´m using RRF 3.01 and a Duet Wifi 2.
After some prints and Calibrations i saw a major problem with printed circles.
They just look like squares.
What i tried:
-Tension of belts
-accleration between 800 to 2000 (got a direct dual drive Bondtech with e3d chimera wich means a heavy weight)
-jerk between 100 to 1200
-printed with cura and simplify3D
I have really no clue about what issues are responsible for these problems.
sry for bad english i´m not a native speaker and thans for some ideas.
This is my config.
